I'm the same way with water.....I never really liked it, but now I find that I crave it! To me, nothing tastes better than an ice cold glass of water
Same with cucumbers. I used to hate cucumbers and really thought they tasted weird. But now I don't mind them....but for some reason, more so when they're cooked or cut thickly. The cucumbers at Subway for instance still creep me out a bit because they're so thinly sliced....haha.
